All you need do is swap the flasher unit for a modern one. This is less time consuming and cheaper. I bought the one in the picture below from Amazon for $10. It has a small adjustment screw (grey colored) which can be turned to control the rate of flashing. The only issue I have with this flasher is that it is silent. You can find a similar product that will emit a clicking sound much like a conventional thermal flasher.

Using the LEDs without resistors will reduce the amperage consumption and the wire harness will appreciate the break.
Will this flasher work on a 69 roundtail? I recently bought leds all around and the stop and rear signals work but the front signals don't flash...also what are the leds for the front parking lights? I ordered what I thought were correct but they too small.
